Guidelines for lifting operations

1 IMCA SEL 019, IMCA M 187 October 2007 Guidelines forLifting OperationsABThe International MarineContractors International Marine Contractors Association (IMCA)is the international trade association representing offshore,marine and underwater engineering promotes improvements in quality, health, safety,environmental and technical standards through the publication ofinformation notes, codes of practice and by other are self-regulating through the adoption of IMCA Guidelines as appropriate. They commit to act as responsiblemembers by following relevant Guidelines and being willing to beaudited against compliance with them by their are two core activities that relate to all members: Safety, Environment & Legislation Training, Certification & Personnel CompetenceThe Association is organised through four distinct divisions, eachcovering a specific area of members interests: Diving, Marine,Offshore Survey, Remote Systems & are also four regional sections which facilitate work onissues affecting members in their local geographic area Americas Deepwater, Asia-Pacific, Europe & Africa and MiddleEast & 019, IMCAM 187 These Guidelines were prepared for IMCA under the direction ofits Marine Division Management thanks its members for their valuable contributions indeveloping this information contained herein is given for guidance only and endeavours to reflectbest industry practice.

10 One survey showed that there could be more than 200 different lifting operationson a vessel. Each lifting operation has a risk of injury to people. Although many tasks are repetitive and of lowrisk, a percentage of them will be of greater risk and will require appropriate scrutiny and input to reduce risksto an acceptable is worth noting that many accidents occur in what are perceived as low risk everyday operations . It istherefore important to ensure that appropriate procedures are in place to try to ensure that lifting teams remainalert to all likely risks regardless of the ease or difficulty of an guidance offers basic criteria. It is based on existing practice collated from major companies, adoptsimproved methods for lifting and is intended to be of use for world-wide guidance is intended to show essential components that should be included in company procedures forlifting operations and offers advice on the steps within a lifting operation process that will promote companies use their procedures in operations internationally, supplemented, if necessary, by anyadditional local regulatory document can be applied to all vessels, their support bases and other shore operations .
